Productivity regime

With this modelling exercise we evaluated the effects of a fixed fishing pressure on the Western Baltic cod population until the end of the century. With the plots beneath you can find the answers to the first to questions on the poster:


What implications do differing perceptions of stock productivity have on the future stock development?

You can see in the plot the observed time series, to answer the question please select in the legend on the right the scenarios:

Depending on the perceived productivity the spawning stock biomass develops differently. The full productivity scenario considers productivity values from the entire time series, whereas the limited scenario time series only takes into account the last XX years. According to recent studies the Western Baltic cod stock is locked in a low productivity regime, thus the limited productivity scenario will probably lead to more realistic results, reflecting the currently depressed stock status.
